CompactFlash Cards™


时至今日,CompactFlash™ (CF) 卡仍是用于嵌入式和工业市场中非常受欢迎的基于闪存的存储解决方案,且 CompactFlash™ 卡外形规格和连接器均很成熟。Swissbit 的 CF 卡的开发重点在于质量、可靠性、稳健性和使用寿命。我们只选择高质量组件,且采用满足客户严苛要求的设计规则。硬件和固件经我们经验丰富的技术团队的测试和验证,经证明,各种功能可适用于很多具有挑战性的客户应用。

Swissbit 的 CF 系列 C-350、C-4×0 和 C-5×0 提供商用(0°C 至 70°C)和工业用(-40°C 至 85°C)温度范围,为各种要求严苛的用例提供坚固和可靠的内存。它们旨在解决从兼容性、启动和断电安全性到长期供应、受控 BOM 和未解决的闪存协议处理技术的各种问题,以确保实现最高可能数据完整性。与普遍推广的顺序性能价值相比,Swissbit 特别关注优化的随机访问速度,这是传统嵌入式 CompactFlash 应用程序中的重要要求之一。

C-350 CF 卡确保与传统系统经优化的向后兼容性,预期可用时间超过 7 年。该系列使用高度可靠的 SLC 闪存(具有 100’000 程序/擦除周期)提供从 32 MB 到 256 MB 的低密度。

Swissbit 的最新 CF 卡产品系列 C-500、C-50 和 C-56 使用基于页面的闪存管理,因此提供最高的写入 IOPS 速率和出色的耐久性。

Data care management
Data Care Management

Various effects like data retention, read disturb limits, or temperature can impact data reliability. The latest generation of Swissbit products use special methods to maintain and refresh the data for higher data integrity.

Electrostatic discharge and electromagnetic interference
ESD and EMI safe

The product designs are in line with the latest regulations for electrostatic discharge and electromagnetic interference. Swissbit strives to exceed these limits with our own in-house technology and production capabilities, for example with System-in-Package (SiP) competence.

Life Time Monitoring (LTM)
Life time monitoring (LTM)

The Swissbit Life Time Monitoring feature enables users to access the memory device’s detailed Life Time Status and allows prediction of imminent failure, avoiding unexpected data loss. This feature uses an extended S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) interface or vendor-specific commands to retrieve the Flash product information.

Power Fail Protection & Recovery
Power fail protection

Intelligent Power Fail Protection and Recovery protects data from unexpected power loss. During an unintentional shutdown, firmware routines and an intelligent hardware architecture ensure that all system and user data will be stored to the NAND.

Secure erase
Secure erase (Sanitize / Purge) / Fast erase

This feature uses an uninterruptable sequence of data erase commands. Even a power off can’t stop the process, which will continue upon restoration of power. The optional enhanced feature allows the customer to sanitize the data according to different standards like DoD, NSA, IREC, etc. The purge algorithm can be started by a software command or through a hardware pin.

Shock & Vibration
Shock and vibration

Robustness is one of our key specification targets. The design, assembly and use of selected materials guarantee an extremely solid design which has been validated by extensive testing.

Write Amplification Factor
WAF reduction

The WAF (write amplification factor) for MLC-based products is reduced by combining a paged based FW block management with a powerful card architecture and configuration settings.

Wear leveling
Wear leveling

Sophisticated Wear Leveling and Bad Block Management ensure that Flash cells are sparingly and equally used in order to prolong life time of the device.

Wide temperature support
Wide temperature support

Swissbit‘s embedded memory and storage solutions are designed and approved for reliable operation over a wide temperature range. The products are verified at temperature corners and prestressed with a burn-in operating functional test (Test During Burn In – TDBI).
